Drag-and-drop labeling items require users to click or touch and hold a label from one area of the screen while moving it to fill in blanks or answer questions on another area of the screen. Depending on the item, labels may be used more than once.
Drag-and-drop items require vision and motor skills to move elements on-screen. Text boxes may be confusing to screen readers. Audio files are not accurate after elements have been moved. Drag-and-drop items cannot be answered with a keyboard or switches. Moving parts cannot be represented in paper-and-pencil, braille, or optical scan test forms.
